It's official. Panda 4.0 has officially hit the Google search results.
The Panda algorithm, which was designed to help boost great-quality content sites while pushing down thin or low-quality content sites in the search results, has always targeted scraper sites and low-quality content sites in order to provide searchers with the best search results possible.
Panda 4.0, which Google and Matt Cutts confirmed began rolling out yesterday, has definitely caused some waves in the search results. However, the fact that Panda 4.0 is also hitting at the same time as a refresh of an algorithm targeting spammy queries like payday loans makes it a little bit more difficult for webmasters to sort through the damage.
With the payday loans refresh impacting extremely spammy queries and Panda targeting low-quality content, some webmasters could potentially get hit with both of these or by just one or the other.
